The Basics of Biosecurity

Intro to Biosecurity

Biosecurity involves a series of management practices that help

  • Keep diseases off the farm (to prevent new infections), and
  • Control diseases on the farm (to prevent them from spreading between animals on the farm or to animals on other farms).

Imagine a bubble surrounding the farm that prevents germs from entering.

Then, imagine a boundary around the farm that keeps germs from leaving.


Biosecurity is the foundation of disease prevention and control on the farm. However, since U.S. farms vary so much, there is no one-size-fits-all approach.

Biosecurity works on all farms regardless of size, animal species, production type, or producer experience.

Your biosecurity plan might be different than your neighbor’s, but you share the same goal: protecting animal health.
